I bought the 6376 (in an HP DL 385p) specifically because I wanted a large number of cores. Recently, I ran into a problem with an application where the number of cores for the 2 CPUs was reported as 16. This limited the number of tasks in the app. While Windows 2012 reports 16 cores per CPU, powershell reports only 8. Logical processors was reported as 16. The queries I used were:

For the record Intel's CPUs have virtual cores, i.e. 4 real cores and 4 virtual as in Non-physical cores. They act as 8 cores but they truly are only 4 physical cores.

How well software is written determines how well it uses all available cores. There is well written software that will use all cores and poorly written software that might effectively only use (4) cores of an 8 or 16 core CPU. The CPU isn't the problem at all. Piss poor code is the problem when the software doesn't use all of the available cores.

Impressive technology. Unfortunately Operating Systems and most applications are years behind. I guess Veeam Backup 7.0 is piss poor code. I have a server running at 2% CPU utilization with Backups taking half a day because Veeam is waiting for resources on the server.

You are absolutely correct. Most so called 64-bit software is just cobbled 32-bit software that shows almost no performance advantage as it's so poorly ported. Windoze 64-bit O/Ss are a joke as far as performance is concerned. AMD CPUs often run programs much faster on Linux.

As far as the floating point unit (FPU), it is essentially a math co-processor. If the code doesn't have a need for FP math then it justs sits idle. If the code is poorly written it might not even use the hardware based FPU, it might use a FPU library. It's actually a disgrace that most consumer level software and O/Ss are so deficient, IMO.
